WIRING SPECIFICATIONS

Wiring and installation methods must comply with national and local electrical code/specifications. The wiring specifications of the PV-system
battery must be selected according to rated currents.

CONNECTION

We strongly recommend connecting a fuse directly to the battery terminal to protect from any short circuit in the battery circuit. PV-modules
generate current whenever light shines on them. The generated current is directly proportional to the light intensity.
Even low levels of light will deliver the PV-Modules no load, full voltage. It is thus utterly advisable to protect PV-modules from any incident light
during installation; Never touch uninsulated cables (ends), only use electric insulated tools, and make sure that the wire cross section is adequate
for the PV module operating currents. Connections must always be conducted in the sequence as described below:
WARNING: The PV-module/array can produce open-circuit voltages more than 100 Vdc when exposed to sunlight
WARNING: Risk of explosion! In case the battery's positive and negative terminals or leads get ever in touch, i.e.,
short-circuited, a fire or explosion hazard might get triggered. Always pay maximum when handling batteries and related
circuits
CAUTION: If no temperature sensor is connected to the controller, the battery temperature value will display the internal
temperature. If a power inverter is used the system, directly connect the inverter to the battery. Do not connect it to the
controller's load terminals.
First step: connect the battery.
Connect the battery cables observing the correct polarity to the center pair of terminals (make sure you identify the battery marking/symbol on the
controller casing!) of the PV charge controller. Pay greatest attention to polarity. Never, ever invert the plus+ and minus- poles). Should your system
be nominal 12 Vdc, make sure the battery voltage is between the 5.0 and 15.5 Vdc voltage range; for 24 Vdc nominal voltage, the battery voltage
should be within the 20.0 to 31.0 Vdc range; for 48 Vdc nominal voltage, the battery voltage should be within the 40.0 to 62.0Vdc. If the polarity is
correct, the LCD on the controller will begin to display those.
Second step: Connect the solar modules.
When connecting the PV-Module make sure to cover it from incident sun light. Double check the PV-Module will not exceed the maximum
permissible input current of the Charge Controller (please refer to the section Technical Data). Connect the solar module connection cable to the
correct polarity of the left pair of terminals on the solar charge controller (with the solar module symbol).
Third step: Connect the loads.
Connect the load cable with the correct polarity of the right-hand side pair of terminals on the solar charge controller (with the lamp symbol). To
avoid the presence of any tension on the cable/wires, please connect these first to the load before connecting them to the charge controller.
Fourth step: Final work
Tighten all cables connected to the controller and remove all the remains around the controller (leaving a void of minimum 15 cm).
